代码点火器与AJAX错误
代码点火器与AJAX错误
提问于 2015-02-11 18:52:53
我在申请酒吧。
当文档准备就绪时，应用程序通过执行#beer_output来使用"beer按钮“填充get_beers_from_customer();。然后酒保通过点击“啤酒表单”按钮来提供饮料。
每次调酒师单击“beers按钮”时，都会发出一个ajax调用，并将其发送到代码点火器控制器，在该控制器中删除啤酒，并响应ajax，将啤酒留给服务，直到没有剩余的订单可供使用。
一旦没有剩下的啤酒，订单就会通过我的控制器的另一个函数：process_order_when_all_drinks_served($user_id)处理。
我使用authorize.net作为支付网关。
问题是我只点了一瓶啤酒，但如果我点了两瓶啤酒，一切都很好。process_order_when_all_drinks_served($user_id)输出试图获取非对象属性的错误。
这里是错误正在发生的具体位置，if($response->response_code=="1")显然没有给出一个响应。ajax正在发布，它不会返回任何错误。我不知道发生了什么。如果有帮助的话，我可以给你点一杯饮料。
以下是ajax函数
$(document).ready(function(){
get_beers_from_customer();
function get_beers_from_customer()
{
//form variables
var user_id = "<?php echo $this->session->userdata('user_id'); ?>" ;
var formData = {user_id:user_id};
ajax_update_content_when_page_is_loaded_beers(formData);
}
function ajax_update_content_when_page_is_loaded_beers(formData)
{
$.ajax({
url : '<?php echo base_url()."index.php/bartender/bartender_serve_beers"; ?>',
async : false,
type : "POST",
cache : false,
data : formData,
dataType: "html",
success : function(data)
{
alert($.trim(data));
$('#beer_output').html($.trim(data));
$('#beer_output').trigger('create'); },
error: function (jqXHR, textStatus, errorThrown)
{
$('#server_message_error_jqXHR').html("here is the jqXHR"+jqXHR);
$('#server_message_error_textStatus').html("here is the textStatus "+textStatus);
$('#server_message_error_errorThrown').html("here is the errorThrown"+errorThrown);
}
});
}
});
once the form is submitted
$(".beer").on("submit",function(event)
{
//variables
var delete_beer = $(this).find(".delete_beer").val();
var beer_id = $(this).find(".beer_id").val();
var user_id ="<?php echo $this->session->userdata('user_id');?>";
// alert( "delete_beer="+delete_beer+"beer_name=" +beer_name +"beer_id="+beer_id );
//form variables
var formData = {delete_beer:delete_beer,beer_id:beer_id,user_id:user_id}; //Array
submit_ajax_form_beers(formData);
//get_beers_from_customer();
});
function submit_ajax_form_beers(formData)
{
$.ajax({
url : '<?php echo base_url()."index.php?/bartender/bartender_serve_beers"; ?>',
async : false,
type : "POST",
cache : false,
data : formData,
dataType: "html",
success : function(data){
$('#beer_output').trigger('create');
console.log($(this).data(formData));
},
error: function (jqXHR, textStatus, errorThrown){
$('#server_message_error_jqXHR').html("here is the jqXHR"+jqXHR);
$('#server_message_error_textStatus').html("here is the textStatus "+textStatus);
$('#server_message_error_errorThrown').html("here is the errorThrown"+errorThrown);
}
});
} 码点火器控制器

$bartender_id = $this->session->userdata('bartender_id');
//load model
$this->load->model('authorizenet_model');

$beer_id = $_POST['beer_id'];
//then it is deleted from the paid beers

$proccess_drinks_message= $this->process_order_when_all_drinks_served($user_id);

我不认为有会话变量输出到前端是不明智的。你也会把它放在下一个控制器里。最好是签入下一个控制器，如果它仍然存在。在其他内部添加一个签入，例如：
//...
else if ($this->session->userdata('user_id') != false && !empty($this->session->userdata('user_id')) ) {
$user_id = $this->session->userdata('user_id');
//continues outputting beers
echo $beers_served_button = $this->bartender_model->output_beers_served_button($user_id);
}//...rest of the code此外，您还检查了$_POST['delete_beer']，而不是将$_POST['beer_id']分配给$beer_id变量。虽然我看不出您通过AJAX传递了任何啤酒变量。据我所见，您只传递会话输出。
